OMG, what they do for 7 days????
It's really expensive.
But the Private Investigator did told me, some Private Investigator company use a lot of manpower for a job, whether is the case easy or not. I hear some of them charge 2k per day.
But it's really wasted if on that unevent day, the Private Investigator lost or the person go out with family then it's too bad.
